Specification of Letters Patent.

Application filed. March 20,1920. Serial 'No. 367,545.

To aZZ whom it may concern:

Be it known that LEDWIN LEROY SMITH, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful improvements in Lace- Braiding Machines, of which the following is a specification. I

My invention relates to new and useful improvements in lace braiding machines, and has for its object to provide an exceedingly simple and efiective device for imparting an intermittent rotary movement to the driver disks for actuating the bobbin carriers, the movement of said bobbin carriers being controlled bya jacquard or pattern mechanism.-

Another object of the invention is to provide means for locking the driver disks after they have made the desired rotation, said locking motion taking place simultaneously with the disengagement of the operating rack from the driver disks. 7

With these endsin view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains, may understand how' to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawings forming a part" of 7 this application, in which Figure 1, is a fragmentary plan view of the raceway plate of a lace making machine illustrating the application of my invention, several of the intersecting'race circle openings being shownwith the driver disks therein, a portion of said plate being broken away to illustrate the location of the operating rac I.

Fig. 2, is an elevation thereof having portions broken away.

Fig. 3, is a section at the line 3-3 of Fig. l.

Fig. 4:, isa plan view of one of the looking disks, and

'Fig. 5, is an edge view thereof showing the manner in which the locking dog engages said disk.

In carrying out my invention as here ejmbodied, 2 and 3 representthe bottom and top plates respectively arranged asiisual in machines of this'character the top plate hav a drive or operatingclutch 8 adapted to be engaged by a clutch arm 9 adjustably secured to each of the rods 10, the latter slidably mounted in the bottom and top plates 2 and 3 and normally forced upward by a spring 11 coiled about said rods and engaging the clutch arm 9 as the movable member and the lower plate 2 asthestationary member and the lower end of each rod lO'has a foot 12 to which is fastened the jacquard operated level" 13 as shown.

The driving clutch 8 is also provided with two upright pins 14 which slidably pass through suitable holes 15 in the driver disks 6 while from the opposite face of the operating clutch depend the downwardly projecting gear pins 16 which are intermittently moved into the path of travel of'the rack 17 which is journaled in suitable brackets 18 and which is driven in any suitable or approved manner.

On the lower end of each post 5 is mounted a locking disk 19 having a squared central opening 20 registering with the squared end of the post 5 and held in place by a nut 21 or its equivalent. At two diametrically opposite points on the circumference of each disk 19 are formed notches 21 which areproduced by partially cutting the metal from said disk and openingthe same upward at convergingangles so as to form centering walls 22 adapted to. be engaged by the wedge shaped nose 23 of thelocking dog 24eadjustably mounted upon the rod 10 so as to move therewith in unison with the clutch arm 9 and when said nose is in engagement with one of the notches 21 the driver disk onthe post carrying such locking disk willlbe centered and securely locked in the desired position.

The'several driver disks 6 with their coacting carrier rest recesses 25 and carrieren, gaging arms 26 operate the bobbin carriers 27 in theusual well known manner for lace making, said bobbin carriers each comprisinga spindle28 and twoopposed disks'29 and 30, one of which rests Il$%i ,1f lldB Of the "top plate '3, Y

From the foregoing description it will be seen that when the rod 10 is actuated by the ward the gear pins 16 will register with the rack 17 and the oscillating movement thereof will rotate the operating clutch member 8 and likewise the carrier disk 4 through the medium of the upwardly projecting pins 14:v

thereby causing thebobbin carrier or carriers which are in engagement with the operated disk to be carried to the opposite side of the race circle and as soon as the movement has been completed and the rod 10 released by the jacquard mechanism the spring 11 will immediately force said rod upward to disengage the gear pins 16 from the rack and simultaneously cause the locking dog 24 to engage the locking disk 19 and if the rotation of the carrier disk was not sufiicient to move the bobbin carrier to the exactly desired position then when the tapered or wedgeshaped nose 23 registers with one of the notches 21 and engages the inclined walls 22 the locking disk will be centered which will obviously move the bobbin carrier to its proper position, i Of course I do not wish to be limited to the exact details of construction asherein shown as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

'Having this fully described my invention, what I claim as new and useful is .1. A lace braiding machine comprising a raceway plate having intersecting race circle openings, a bottom plate, bearings mounted in said bottom plate, centrally of the race circle openings, posts journaled in said bearings, a driver disk carried by each of said posts and located inthe race circle openings, an operating clutch member'slidably mounted on each of said posts, upwardly V projecting pins carried thereby and slidably set mounted in the coacting driver disk, gear pins depending from said operating: clutch member, an oscillating rack adapted to, be

engaged by said gear pins whereby a rotary motion may be transmitted to the driver disk, and means for slidingthe operating clutch member on its post to move the gear pins into the path of travel of the rack.

2. A lace braiding machine comprising a raceway plate having intersecting race circle openings, a bottom plate, bearings mounted in said bottom plate, centrally of the race circle openings, posts journaled in said bearings, a drlver'diskcarried by each of said postsrand located in; the race circle openings, an operating clutch member slidably mounted'on each of said posts,v upwardly mounted in the coacting driver'disk, gear pins depending'from said operating clutch member, an oscillating rack adapted to be engaged bysaid gear pins whereby a rotary motion may be transmitted to the driver disk, a rod slidably mounted in the plates adjacent each post, a clutch arm adjustably mounted on said rod and engaging the operating clutchmember for actuating the latter when the rod is moved by the jacquard or pattern machine, and means for normally forcing'said rod in that direction which will force the operating clutch member upward or out of engagement with the rack.

3. A lace braidingmachine comprising a raceway plate havingintersecting race circle openings, a bottom plate, bearings mounted in said'bottom plate, centrally ofthe race circle openings, posts journaled in said bearings, a driver disk carried by each of said posts and located in the race circle openings, an operating clutch member slidably mounted on each. of said posts, upwardly projecting pins carried thereby and slidably mounted in the coacting driver disk, gear pins depending from said operating clutch member, anoscillating rack adapted to be engaged by said gear pins whereby a rotary motion may be transmitted to the driver disk, a rod slidably mounted in the plates adjacent each post, a clutch arm adjustably mounted on said rodjand engaging the operating clutch member for actuating-the latter when the rod is moved by the jacquard or pattern machine, means for normally forcing said rod in that direction which will force the operating clutch member upward or'out of engagement with the rack, a locking disk secured to each post, saidlocking disk having diametrically opposite notches in its outer circumference with converging centering walls and a locking dog adjustably mounted on each rod having a wedge shaped nose for registration with the notches in the locking disk, said dog being operable simultaneously with the operating clutch member.

4. In a lace braiding-machine, a raceway plate, abottom plate, postscarried'bythe bottom plate and projecting through the whereof I have signature,
